BEATER FOR MANURE-SPREADERS.

Specification of Letters Patent.

Patented July '7, 1908.

Application filed January 20, 1908. Serial No. 411,690.

T 0 all whom it may concern:

Be it known that I, STINSON ROBINSON, a citizen of the United States,residing at Vinton, in the county of Benton and State of Iowa, haveinvented certain new and useful Improvements in Beaters for Manure-Spreaders; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the samcf Myinvention relates to new and useful improvements in beaters for manurespreaders, and my object is to form the beater in two sections and taperthe same from their meeting to their outer ends.

A further object is to provide means for mounting the beater in positionon the bed of the spreader.

A further object is to so mount the two sections of the beater, that theperipheral faces thereof will be parallel with the apron of thespreader, whereby the beater may be located atthe end of the apron,instead of over the top thereof and a still further object is to providemeans for rotating the sections of the beater in unison.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying drawings which are made a part of this application,Figure 1 is a side elevation of the rear end of a manure spreader,showing my improved beater attached thereto. Fig. 2 is a sectional viewthereof, as seen on line 2-2, Fig. 1. Fig. 3 is a detail, perspectiveview of a portion of one of the spiders employed in forming a beater,and, Fig. 4 is a perspective view of one of the bars employed forcarrying the beater prongs.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indi cates the bedof a manure spreader, at the bottom of which is mounted an apron 2, saidapron being disposed around guide rollers 3 and is moved longitudinallyof the bed 1 to convey the contents of the bed to the rear end thereof,motion being imparted to the apron from the rear axle 4 through themedium of gears 5 and 6 and intermediate gears (not shown).

In order to disintegrate the manure as it is moved to the rear end ofthe bed 1 and uniforn'nly spread the same over the ground, I

provide my improved form of bcater, which is formed in two sections 7and 8, said sections consisting of spiders 9 having cars l() thereon,upon which are adapted to rest bars 11, said bars being secured to thecars by means of bolts 12 and in order to readily secure the bars inposition on said ears, each ear is provided with a slot 13 extendinginwardly from one edge of the car, so that after the bolt is enteredthrough the bar, the inner ends thereof may be seated in the slots andthe bar clamped in position on the cars by meal s of nuts 14 on thethreaded ends of said bolts. The outer faces of the bars 11 arepreferably inclined from their outer to their inner ends, so that whenthe bars are all assembled, the inner ends of the sections will begreater in diameter than the outer ends thereof, the object in soconstructing the sections, being to give a greater outward throw to themanure, thus covering a greater surface of the ground than when thebeater is the same diameter its full length. If preferred, however, thespiders at the inner ends of the sections may be increased in size, inwhich event the upper faces of the bars 11 should be parallel with thelower faces, the increased diameter of the inner spiders giving theinclined )itch to the bars. The spiders 9 are provided with tubular hubs15, which are adapted to receive and rotate upon a shaft 16, said shaftbeing fixed at its ends to brackets 17 carried by the end of the bed 1,and in order to bring the ta )ered outer faces of the bars 11 parallelwith the apron 2, when said bars are in juxtaposition to the apron, theshaft 16 is bent outwardly at its longitudinal center, thereby disposingsaid sections in dill'erent'axial planes and bringing the meeting endsof the bars 11 substantially together adjacentthe apron. Each of thebars 11 is provided with a plurality of prongs 18, which extend adistance from the outer faces of the bars and are ad opted to engage themanure carried by the apron and remove and scatter the same as thesections of the beater are rotated and, if preferred, the prongs on eachalternate bar may be staggered and caused to travel ina different pathfrom the prongs on the opposite bar and the shaft 16 is so located thatthe prongs will just clear the apron in their i otating movement and ithas heretofore been the custom to extend the apron below the beater,thus adding additional stram on the draft animals, in view of the factthat the weight of the whoie load is practically pressing against thebeater so arranged, but by constructing the beater in the manner hereinshown, this obgectionable feature is overcome, from the fact that thesections oi the beater extend slightly below the upper surface of theapron and in the rear thereof, this manner of locating the beaterremoving the pressure of the entire load of manure from the beater, andat the same time, permittingthe beater to remove all particles -from theapron.

The beater 7 is driven from a shaft 19, to which the gear 6 is secured,by means of a sprocket chain 20, which chain extends around a snrocket21 on the shaft 19 and around a similar sprocket .22 on one of the hubsl5, chain :20 being guided onto the sprocket 22 by means of a guideplate 23 carried by one of the brackets 11 while tension is directedonto the chain by means of an idler 24 carried by an adjustable arm 25,the

lower end of which arm is secured to the.

bed i.

The section 8 is simultaneously rotated with the section 7, by securingto the ends of a portion of the bars ill forming the section 7, plates26, the ends of which. project beyond the inner ends of the bars 11, towhich they are secured and engage corresponding bars-11 on the section8, thereby causing the section 8J0 rotate with the section 7, or spursor teeth may be placed on t meet ng faces of the inner spiders in suenor as to intermesh with each other said ar'nigart rotating movement tothe section 8.

it will thus be seen that l have provided a very cheap and efficientform of beater for use in connection with a manure spreader and onewherein the manure will be given an outward throw and spread over aconsiderable surface of the ground.

It wili further be seen that by arranging the sections of the heater inthe manner shown, all the particles will be removed from the apron andthe strain upon the animals re uired to operatc tlie sci-coder, reduced.

1: will further be seen that by tapering the outer faces of the barsforming the sections of the beater, or enlarging the-inner spiders, themeeting ends of "the sections will greater in diameter than the outerends thereof, thus causing the contents of the spreader to be thrownoutwardly or laterally Spreaders,

set

and the ta: cred faces brought parallel with manner shown.

What I claim is: i v

1. The herein described beaterfor manure comprising the combination witha bed and means to move the contents of the bed to the rear end thereof,of a beater formed in two sections, the meeting ends of saidsectionsbeing greater in diameter than the outer ends thereof, said sectionsbeing so the apron y extending the shaft 16 in the .niounted one withrelationto the ot lieithat the faces thereof when opposed to this body,aline, and means to simultaneously rotate said sections. I v A beater ofthe class described, said beater being formed in two sections, themeeting ends of said sections being reater in diameter than the'oppositeends t ereof, I:

eachsection consisting of a pair of spiders, laterally extending ears onsaid spiders, a plurality of bars carried-by said spiders, the,

outerfaces-of which areinclined, a plurality v y of prongs carried bysaid bars, means to secure said bars to the spiders and additional meansto rotate s'aid' sections in unison.

3. A heater of'the class'describejd, comrising the combination with ashait; of

eater sections, said sections comprising spiders of equal diameter, barscarr ed/ b said spiders, the outer faces of which at clined, whereby theinner'ends O;,;St1d

SGC- tions will be greater in diameter than the outer ends thereof, sa1ds ect1ons beingso mounted, that when said bars are in onepoe,

sition, the tapered faces of two of the bars will rest in the samelongitudinal plane.

i. A beater of the classdescribed, conithe combination with a shs fttofa pair or oeater sections mounted on said smut,

the meeting ends of said sections being greater diameter than the outerends thereof, s id shaft bent at a point be tween the two sections,whereby the axial centers of said sections will be in different planesand means to rotate said sections unison. V

in testimony whereof I hays signed m name to this specification iii-thepresence of two subscribing witnesses.
